Library and Component Information

Management

PADS Professional has an integrated, correct-by-

construction component library ensuring that once a part

is defined, the symbol, cell and part mappings will be

in-sync. This approach eliminates a major cause of design

iterations commonly found in netlist-driven design

solutions.

What value is the component library if you can’t find the

parts you need? With PADS Professional it’s not a problem

because all component information is included in an easy-

to-use query and verification system that accepts

component information from your choice sources.

Individual engineers and small workgroups often don’t

have the time or resources to develop a corporate library

that adheres to both company and industry standards.

PADS Professional delivers an industry-proven starter

library that has been developed over several years in a

PCB design production environment. This library includes

schematic symbols and PCB footprints that will enable you

to start designing immediately. There’s no need for you to

spend valuable time searching for manufacturing

datasheets and building your own library from scratch

The starter library contains over 11,000 current

manufacturer’s part numbers including a wide variety of

device types, well-defined

partitions for easy navigation,

and descriptions of the

standards which were used to

create the library, which is also

IPC-7351B compliant.

Design Archive

Management

Engineers like to try a multitude

of “what-ifs” during the design

cycle. The problem is keeping

track of it all — file naming

conventions just don’t cut it.

PADS Professional includes an

intuitive design archive manager

allowing engineers to create

and restore design archives,

view and compare different

archives, and create custom

reports.

Design Definition

PADS Professional allows schematic or table-driven design

entry of digital, analog/mixed signal, and RF circuits.

Unlimited hierarchy lets you organize your design and

makes for easy design reuse. If you are using hierarchy, you

will need the powerful search and edit capabilities that are

hierarchy aware.

Variant management allows you to reuse a single

schematic for different variants of your design, and this

capability extends into layout as well.

Project and design navigation is intuitive while the built-in

component information browser allows you to easily

research and instantiate parts on your schematic.

Extensive rules checking eliminates errors prior to layout,

increasing the quality of your design. Tight integration,

including cross probing, keeps your schematic, constraints

and layout in sync at all times allowing you to manage

and track changes as your design progresses.

FPGA Synthesis

Now that FPGAs have become as complex, in many uses,

as ASICs and SoCs, advanced FPGA implementation flows

must be adopted by hardware engineers. Synthesis is a

critical component of an integrated, FPGA vendor neutral

design environment. By delivering high quality results and

FPGA synthesis is much simplified using the PADS Professional FPGA implementation flow.

www.pads.com

offering industry-specific requirements,

PADS Professional offers breakthrough

advantages for FPGA applications. The

implementation flow supports

applications ranging from commercial

datacom and telecom designs through

automotive to military-aerospace and

safety-critical systems that require not

only performance but also specific

system requirements such as power

efficiency.

Because more FPGAs are being designed

into low-power applications, you not only

need to carefully select the most power

efficient device but also must ensure their

implementation flows reduce device

utilization and power to the greatest

extent possible. Starting with design

entry and compilation, PADS Professional

offers leading edge HDL language

coverage for proficient interpretation and

optimization from HDL to the target FPGA

architecture resulting in smaller and faster designs.

Likewise, architecture specific optimization for each FPGA

device fully utilizes architecture specific features and

advantages to meet design requirements.

FPGA I/O Optimization

Today’s FPGAs are very powerful devices with high pin

count, numerous I/O standards and high speed

capabilities. In addition, advanced implemented logic in

the FPGA very often requires that hundreds of logical

signals be mapped to physical

signals. This is a challenge for hard–

ware engineers to match the HDL

world with the electrical world.

An automated FPGA symbol gen–

eration process typically saves as

much as 30X over traditional man–

ual processes. The process uses

correct-by-construction, rule-driven

I/O assignment with a library of

FPGA vendor devices, including early

access to not yet released devices.

In light of these challenges, PADS

Professional fully supports FPGA-on-

board integration, reducing time to

market and manufacturing costs

through reduced layer counts, via

counts and design cycle time.

Achieving Electrical Sign-off

PADS Professional includes a powerful and fast design

rule checking tool . It verifies complex design rules that

are not easily simulated, such as rules for EMI/EMC. With

support for design rule checks for items such as traces

crossing splits, reference plane changes, shielding, and

via checks, you can quickly and easily pinpoint trouble

spots on your board that can cause issues with EMI/

EMC, signal integrity, and power integrity.

PADS Professional bridges HDL-based FPGA design and PCB design for automated, fast

and error-free, bi-directional information exchange.

Design rule checks can be performed on boards for EMI/EMC issues, as well as signal integrity

and power integrity issues. It is highly customizable, allowing users to create DRCs

for any check they might otherwise perform manually.

www.pads.com

The combination of design rule checking for full-board

screening, coupled with advanced signal/power integrity

analysis, provides you with a fast, accurate solution for

achieving electrical sign-off.

Constraint Management

As PCBs increase in complexity and density, a higher

percentage of the design must be implemented with strict

adherence to design rules. Manual documentation,

translation, and interpretation of design rules often cause

longer product development cycles and increased costs.

The constraint manager provides a fully integrated,

constraint-driven design methodology that reduces design

costs and time-to-market by automating design rules

communication and eliminating unnecessary PCB

prototypes and re-spins. The constraint manager provides

the engineer with direct control over the PCB layout.

The constraint manager supports bi-directional cross

probing, highlighting and selecting between a spreadsheet-

based constraint interface, schematic capture and PCB

layout. Any net can be analyzed for signal integrity pre-

layout when developing a topology template, which can

then be used in the constraint manager.

As the number and complexity of constraints explodes, the

constraint manager comes with a lightweight, easy to learn,

context-sensitive tool for editing constraints within the

schematic or PCB layout.

Analog/Mixed-Signal

Simulation

PADS Professional includes advanced

circuit simulation with

comprehensive analysis for analog,

mixed-signal, and mixed-technology

PCB circuits. Bring circuits in from

PADS AMS Cloud to drive simulation

and PCB, then use powerful SPICE

and VHDL-based technologies to

help understand and verify circuit

behavior.

With PADS Professional you can also

optimize for real-world variability by

exploring various scenarios to

determine which parameters or

conditions most affect circuit

performance.

Thermal Analysis

PADS Professional incorporates thermal analysis to allow

engineers to analyze board-level thermal problems on

placed, partially routed, or fully routed PCB designs.

Temperature profiles, gradients, and excess temperature

maps enable engineers to resolve board and component

overheating early in the design process.

Integrated thermal analysis allows engineers to detect potential heat

problems without expensive prototyping.

Powerful data measurements, waveform viewers, and post-processing calculators speed review

and analysis of analog, mixed-signal, and mixed-technology circuits

Signal Integrity Analysis

PADS Professional offers powerful and easy-to-use signal

integrity capabilities, including DDRx validation. With pre-

layout analysis capabilities for defining stackup and

routing constraints, to verification of the routed board to

ensure your design goals are met, PADS Professional offers

a rich environment for your signal integrity analysis needs

based on renowned HyperLynx technology.

Power Integrity Analysis

The power integrity analysis environment is easy to set up

and use, getting simulation results without requiring

weeks of software training. You can identify power

distribution problems early in the design, even prior to

layout. You can also identify IR drop problems with your

design that would be difficult to identify in the lab, and

investigate solutions in an easy-to-use “what-if”

environment. Once the layout is complete, you can

validate the results to ensure that appropriate guidelines

were followed. This will ultimately help you reduce

prototype spins and get to market faster, while creating

more reliable products.

PCB Layout

At the heart of PADS Professional is the industry’s most

powerful PCB layout technology, all within a single editing

environment. Xpedition technology is used to design the

world’s most complex boards that include complex,

constrained topologies and power distribution, differential

pairs, wide busses, HDI, flex and large, fine pitch BGAs.

PADS Professional supports a correct-by-construction

approach that produces high quality results and reduces

costly iterative clean-up of constraint violations. Dynamic

glossing of traces reduces segments, prevents acute

angles and obeys pad entry rules. Dynamic high

performance healing of planes and thermal reliefs allows

real time creation of complex power distribution

topologies. Fully integrated, true parametric, 3D layout

with placement, constraints, DRC checking, and photo

realistic visualization minimizes MCAD iterations.

Tight integration makes power integrity analysis easier to use.

New routing technology allows the designer to sketch the path of

signals, then the interactive router efficiently routes those traces. In

the top image, the designer has “sketched” the path desired for the

signals shown in purple. In the bottom illustration, the Sketch Router

has efficiently routed the traces according to the designer’s sketch.

The analysis environment is tightly integrated with schematic

and layout, simplifying signal integrity analysis.

www.pads.com

PADS Professional includes revolutionary placement and

interactive routing technology focused on productivity.

Hierarchical group placement allows you to place your

board taking advantage of natural or defined component

groupings in your design. PADS Professional combines

automatic and interactive technology keeping you in

control while automating the more mundane tasks. You’ll

be amazed at the sheer power of the glossing, push and

shove during trace manipulation.

Sketch Router

In addition, the ground-breaking sketch routing in PADS

Professional takes productivity to a whole new level.

Taking your design intent and routing strategies in the

form of a super-efficient sketch, the system automatically

fans out, untangles, and routes the associated nets with

the quality of an experienced PCB designer. Sketch routing

reduces complex routing times by orders of magnitude.

Starting with the Sketch Router, a designer can draw a

sketch path to dictate the location for the routing of the

selected netlines. The Sketch Router will route individual,

dozens, or even hundreds of netlines many times faster

than manual routing. Sketch routing focuses on quality;

little cleanup is needed, often none at all. The high routing

completion rate (typically >90%) is due to its ability to

automatically optimize the escapes from components like

BGAs so they are optimal for routing without any

additional vias.

3D Layout

One of the challenges to integrating your PCB design

process into the electromechanical world is the ability to

“left-shift” validation into the PCB layout processes to find

electromechanical design problems early, eliminating

costly re-design late in the cycle. 3D layout is a fully

integrated 2D/3D environment using the same selection,

planning and placement functionality as PCB layout.

The true parametric 3D mechanical kernel uses a

complete set of 3D constraints with dynamic collision

detection and batch verification to ensure your

electromechanical designs are error free. Full photo-

realistic visualization of board elements, like traces,

components, silk screen, solder mask, and vias, is provided

with transparency, z-axis scaling, view/ rotation control,

and x/y/z cut planes.

Included with 3D layout is a ~4.5 million-part 3D model

library . The ability to import your own models from STEP

files is also available. Models are easily mapped and

aligned with included library tools. You can also import

mechanical components like chassis and heat sinks, and

even sub-assemblies of other PCB designs, providing true

mechanical multi-board capability.

Once your design is complete, you can use the integrated

MCAD Collaboration tool to pass information to popular

industry mechanical design systems. You can also export

your design in standard industry formats, and utilize the

3D PDF and documentation tools to complete your design

package.

3D visualization, placement and validation optimizes PCB

electromechanical design.
